Ist snapchat.com sicher?

Quote from Naked Security: "Be prepared to laugh (or cry - it's not really funny): according to Hickman, "expired" Snapchat photos don't disappear at all! He grabbed a forensic image of a phone running Snapchat, found a directory called received_image_snaps and looked in it. Both unviewed and expired images were still there. If Hickman's analysis is correct (and it certainly seems to be), Snapchat relies on two steps to make your images "disappear": It adds the extension .nomedia to the filenames, which is a standard Android marker that says, "Other apps should ignore this file. Do not index it, thumbnail it, add it to any galleries, or whatnot. Leave it to me." It adds a record to its own database to say, "The following image should be treated as though it doesn't exist. Leave it to me, and I will pretend it has disappeared forever."" Source: ***** Conclusion: Please DO NOT upload sensitive photos of yourself as photos are easily retrievable...far from gone forever!
